vmnarron-nncoimm I Specification of Letters l'atent. Patented July 15, 1919.

I Application filed October 2, 1918. Serial). 256,814.

To all whom. it may concern Be it known that I, HANS SATTIER, a citizen of the United States, and resident of Sheboygan, in the county'of Sheboygan and State of Wisconsin, have invented certain new and useful Improvements in Vibration- Recorders; and I do hereby declare that the incidental to the running of automobiles or other vehicles, and to thus afford a positive indication of the amount of'running time of the vehicle within a certain period, and gen eral conditions of speed and roughness of travel to which the vehicle is subjected.

It is in general the object of myinvention o simplify and otherwise improve the structure of recorder devices of this character,

with a view to increasing the durability of such devices in continued use, and with a view to increasing the recording efficiency of such devices. 1 I

As in my said patent, I contemplate the use of a conventional clock mechanism for driving the record dial, and it is more particularly an object of my invention to provide an improved mounting for the clock mechanism whereby it may be most read'ly associated with a record dial, and whereby to avoid the setting up of unduestress in the clock mechanism incidental to its association with the recording dial.

it further. object resides in the provision of an exceedingly compact arrangement of the various parts as heretofore mentioned, whereby the parts may be inclosed in 9. casing to protect the parts and prevent interference with their desired functions.

With the above and other objects andadvantages in view, which will be apparent as the description proceeds, my invention, resides in the novel features of construction, combination and arrangements of parts as hereinafter described and defined by the ,appended claims.

In the accompanying drawings:

Figure 1 is an elevational view of the casing of my improved vibration recorder, the

door of said casing being swung open, and the recording mechanism being shown in the casing vin section, line 11 of Fig. 2.

F ig. 2 is ;a sectional view through the mechanism and casing wit'h the door closed, on the broken line 22 of Fi 1.

Referring now more particularly to the drawings, there is provided a .casing includas indicated by the ing a back wall 5 and a peripheral wall 6 to one side of which is hingeda door 7 forming the front wall of. the casing. The back wall carries a pair of hook lugs 8 at its upper portion engageable over any desired support member on the vehicle, and the lower portion of the backwall is provided with an apertured inwardly extending boss 4 8 for the reception of a screw to be engaged in the support member over which the hook lugs 8 are engaged, whereby to lock the casin'g against detachment. Since communication with the interior of the casing is controlled by the door 7 which would beprovided with conventional lock mechanism (not shown), removal of the casing without proper authority is impossible.

A carrying plate 9 is secured eccentrically in the casing by screws 10 passed through its peri heral portion and engaged in a set of, .in t he present instance, three studs 11 projecting inwardly from the back wall 5 of the casing, the plate being thus held parallel with and spaced from the casing. This plate is apertured for the reception of the usual attaching screws 12 projectingfrom one of the assembled side plates 13 of a conventional clock mechanism unit. This clock mechanism includes the main spring 14 mounted on a shaft 15, andthe clock mechanism and its carrying plate 9 are so disposed relative to the casing that the main spring shaft 15 is disposed axially in the casing and consequently adjacent one side of the carrying plate. 'A sleeve 16 projects 4 forwardly from the carrying plate axlally of the casing, and in carryin outmy inven- I tion I secure a-gear wheel 7 on the main spring shaft of the clock mechanism, this gear wheel carrying a squared winding stud 17 which extends into the sleeve 16 for engagement b any suitable winding keyfinsertible in t e sleeve. The plate 9, inwardly of the sleeve 16 has a portion ofl'set tol form a well 18 open at the side of the plate adjacent the clock mechanism, and projecting portion of the plate and on which is mount into this well is a pin 19 carried by the ofi'set ed a gear wheel 20 which meshes withthe gear wheel 17 of the winding shaft 15 and which is rigidly connected with a pinion 21 disposed in the well and projecting at the forward side of the plate 9 through a cutaway portion of the well. This pinion meshes with a series of gear teeth 22 carried on a journal sleeve 23 which is mounted on the sleeve 16. The intermediate portion of the sleeve 23 carries a seating plate 24 for the indicator dial structure, later to be described.

By the foregoing construction, a conventional clock mechanism may be associated with a record dial for driving the same, in

a most economical manner, and in a manner avoiding the imposition of any unusual stresses upon the. clock mechanism which might interfere with its accurate continued operation. It is noted that the clock mechanism is carried entirely by the plate 9, which also carries the recording dial plate 24 in an independent manner. The clock mechanism is thus mounted in a manner practically identical to its mounting in an ordinary clock casing, and i the operative conditions for which it is conventionally designed are thus retained. The only modification of the clock mechanism is the attachment of the gear 17 to its winding shaft.

1n the present arrangement, for procuring the record, a sheet of car bon or similar paper L 25 is placed against the seating plate 2a and the record disk 26 is placed against this carbon sheet, both sheets being held against rotation on the plate by a spur 27 projecting forwardly from a peripheral portion of the plate. The record sheet is supported by a backing plate 27 which is secured against the plate by a collar 28 engageable on the outer end of the journal sleeve 23 and provided with looking pins 29 of conventional nature engageable in slots of the journal sleeve for procuring a quick detachable connection. It may be noted at this point that the journal sleeve is held assembled on the sleeve 16 by a nut 30 threaded on the forwardly projected end of the sleeve 16 and bearlng against the end of the journal sleeve, and this nut is of lesser diameter than the journal sleeve whereby to permit detachment of the collar 28 and backing plate for ready removal and replacement of record sheets 26. g

For marking the record sheet, an-angular pendulum lever is pivoted at its angle in the bifurcated end of a bearing bracket 31 secured to the upper portion of one side of the back wall. 5, this lever including a vertically depending weight arm 32 and a rel.

atively short inwardly inclined arm 33 carrying a transverse head 34 in which is disposed a stylus 35 engaging the carbon sheet 25, this stylus being preferably yieldably urged to project from said head in the manner of my said previous patent, although be indicated by the magnitude of the vibrations, as recorded on the record sheet 26 by the stylus 35.

Thus an accurate record may be obtained of the conditions to which a vehicle is subjected in a given period of time, and my device is preferably so arranged as to procure a single rotation of the record sheet in a twenty-tour hour period, it being noted that a reduced train of gears formed by the various gears and pinions heretofore specifically described, is interposed between the winding shaft 15 of the clock mechanism and the gear teeth of the journal collar to effect this operation.

To limit the oscillatory movements of the weight arm 32, a pair of studs 36 project inwardly from the back plate 5 at the sides of said. weight arm, and inasm ch as he casing may be tilted to one side or the other in its attachment on a vehicle, it is desirable to provide a horizontal ad ustment for those studs whereby the proper oscillatory play of the weight arm may be determined under such conditions. To this end, the studs 36 are mounted on a bracket plate 37 which is provided with a horizontal adjusting slot 38 through which are. screws 39 clamping the plate to the back wall 5.

The peripheral wall of the casing is provided at substantially its central portion with an annular inwardly extcndin partition flange 4.0 which projects inwa ly to a point adjacent the periphery of the seating plate 24, this flange being preferably integral with the peripheral wall of the casing, which in turn is integral with the back wall, thus providing an exceedingly solid and simple casing structure. This partition flange is provided with a transverseslot 41 receiving. the stylus head of the pendulum lever, and the lower portion of the. flange is apertured at 4:2 to permit insertion of the securin screw of the casing in the boss 8 of the bac wall.
